Answer question 7

D) Shells A and C were in the air for equal time, which was longer than for shell B. 6. A projectile is fired into the air at some angle above the horizontal. The horizontal displacement of 16- the projectile is measured against time in flight and the collected data is shown as a horizontal displacement versus time graph at the right. Based on this graph, the horizontal velocity of the projectile Horizontal Displacement (m) 8 during this time interval is: A constant. B) increasing. C) decreasing. D) equal to zero. O O 2 Time (s) 4 7. On the graph from question #6, draw the graph of Horizontal Displacement vs Time that would occur if air resistance was included. 8. List four assumptions that we make for our projectile motion equations to work. the four assumptions that we should or typicany make for the projecticice motion equations to way the- the we have to study the motion of the Projectile motion, we have to assume that (i) there is or willb frictional resistance of the air. (1i) The CFFect due to the rotation of earth and the curvature of the earth or should be negligibic, line , thereithe the accciaction to dock the gravity is constant in the ve
